jsonP response not displaying on client context window

Hi

I am able to add jsonp response of service: http://api.wipmania.com/jsonp?callback=${callback} to client context. Selected two properties latitude and longitude. On save the property along with value is getting reflected on the client context edit content page:

http://localhost:4502/etc/clientcontext/default/content.html.

But when I access the client context on any website page it says: No latitude and No longitude.

Can you please let me know what I am missing here so that the jsonP property displays on client context window when opened on other pages.
